How can I disable this message? - ruby-on-rails

Question

I'm using the gem called "rails3-jquery-autocomplete" ( https://github.com/crowdint/rails3-jquery-autocomplete )
It's working fine:) But there's one thing that I want to disable.
When I type something into an input field, and there's no matching record, it always show the message that's saying "no existing match"
I want to disable this message. Is it possible?
I wish I could see inside of its source code to customize but I cannot :(
Anyone can help me about this?
This might be piece of cake for someone but not for me.
For your information, I've done this command below
$ bundle exec rake assets:precompile RAILS_ENV=production
and after this it created some js files into public/assets folder

Seems there is no way to pass option into the control, but I assume this might be a trick to solve your problem.
Instead of returning empty array(from backend) when no search results, try to return a array with one result has empty id and label might solve your problem, so in your rails controller, there will be something like this:
def autocomplete_action
result = do_the_search
if result.count == 0
result = [{ id: "", label: "" }] # !! do the trick here
end
respond_with result # assume you have "respond_to :json" in your controller
end
Here is why I am doing this:
The reason why I think this might work is because if no result return, the autocomplete control will build a fake record with id equals to empty represent no result.
if(arguments[0].length == 0) {
arguments[0] = []
arguments[0][0] = { id: "", label: "no existing match" } // hacked here
}
But I do think this definitely not the right way to solve this problem, but for now it's workaround to solve your problem quickly.
Hope it helps, thanks.
